Summary of the invention
The object of the invention is, a kind of self-propelled soil compaction is set, scratch device wherein can be made in a straightforward manner to disengage with the compression roll matched.
This object is reached by a kind of self-propelled soil compaction according to the present invention, it at least one scratch device comprising at least one compression roll and match with at least one compression roll, described scratch device be included in supporting arrangement can support with deflecting and work inflection point in be in the compression roll matched the strigil contacted, for the action bars of deflecting operation strigil and the locking device for being locked in the strigil that at least one shut-down inflection point disengages with the compression roll matched, locking device has to the pre-tensioned locking member in direction of active position and can enter with locking member the pairing locking member locking and rabbet in order to the locking of strigil in shut-down inflection point, locking member can regulate between active position and un-activation position, in active position, locking member is in maybe can enter to lock with pairing locking member and rabbets, and be not in maybe can not enter to lock with pairing locking member in un-activation position and rabbet, pairing locking member on arrange be used for locking member push inclined-plane open, when strigil deflects from work inflection point to shut-down inflection point, pushing inclined-plane open makes locking member move towards un-activation position, and locking member enters to lock with pairing locking member and rabbets when strigil reaches shut-down inflection point.
By the deflectable installation of strigil and first strigil configuration operation bar is become easy it is possible that by the reciprocation of operating personnel make strigil away from match compression roll deflection.In the location that such deflection is left, general in shut-down inflection point, strigil can be stoped to the return movement in the direction of the work inflection point of this strigil by arranging locking device and therefore guarantee the spacing of the determination between strigil and compression roll, such as, in order to clear up compression roll or in repairing or maintenance work.
In order to guarantee reliably power to be imported strigil, suggestion operations bar is connected to strigil jointly to deflect in FX, and action bars has the force region for importing deflecting operation power.
According to the configuration of compression roll at which altitude range, scratch device is arranged in soil compaction, the reciprocation favourable for the ergonomics for operating personnel can advantageously, and action bars is configured to foot rest or/and be configured to handle.When being positioned in the region closer to basis, ordinary priority is considered as the form of implementation of foot rest, and the form of implementation when being positioned in higher region generally as handle can be favourable, be certainly designed to action bars to be not only used for that foot operation indulges but also be used for manual operating is possible.
In order to the locking of strigil at its shut-down inflection point can set, locking device has locking member and can enter with locking member the pairing locking member locking and rabbet in order to the locking of strigil in shut-down inflection point.To this in order to improve functional can setting further, locking member can regulate between active position and un-activation position, in active position, locking member is in maybe can enter lock rabbets with pairing locking member, and in un-activation position with match locking member and be not in maybe can not enter to lock and rabbet.If at this locking member at its active position, then can guarantee, strigil remained on the shut-down inflection point of this strigil or certainly lead to such maintenance interaction when moving to shut-down inflection point from work inflection point.If locking member is in its un-activation position, even if then can not produce locking action when moving to the direction of shut-down inflection point, therefore strigil can not be locked in the shut-down inflection point of this strigil by locking device.If such as only should mention from the compression roll matched in short-term, therefore deflect and open strigil, but do not need or do not wish when the locking of shut-down inflection point, then can select this un-activation position of locking member especially.
In order to the locking phase mutual effect between locking member and pairing locking member can be provided in a simple manner, suggestion, pairing locking member has at least one locking member backstop that can be acted on from behind by locking member, wherein can advantageously set, at least one locking member backstop is provided by the lock opening of pairing locking member.
Needing structurally simple realization and advising about simple manipulation in favourable design, pairing locking member is arranged on supporting arrangement and locking member can deflect with strigil.Such as can locking member be arranged on action bars at this, thus to action bars effect for deflecting strigil time also can handle the locking member at this moment arranged on action bars, such as this locking member can be delivered to its active position from its un-activation position.
In order to reliably be embodied as the function that scratch device is arranged in the operation of soil compaction, suggestion, strigil is pre-tensioner to its work inflection point.

Detailed description of the invention
Totally by the soil compaction of 10 marks shown in Fig. 1, generally also referred to as compression roll.Soil compaction 10 comprises vehicle region 12 below, the vehicle region after this is also arranged unshowned drive unit, driver's cabin 14 and in order to advance by each wheel 16 that drive unit drives.Vehicle region 18 above can be connected with vehicle region 12 below with deflecting, and closing vehicle region 12 later by vehicle region 18 above can affect travel direction around the deflection of the yawing axis of perpendicular and thus also can affect operative orientation.
Vehicle region 18 above arranges compression roll 20.Unshowned shake or oscillation drive can be configured, to make compression roll 20 be in vibration and affect compacting situation thus when soil compaction 10 travels forward for this compression roll.Compression roll 20 comprises generally also referred to as the shell 22 of smooth rim, and the surface 24 of the outside exposure of this shell is in the basis 26 of compacting and contacts.
The structure can found out in FIG iting is noted that self-propelled soil compaction 10 is here exemplary.Can be changed it in very different.Therefore may replace the vehicle region 12 of each wheel 16 is below arranged another for front and then can driven compression roll 16.Also may above and/or vehicle region is below settled two compression rolls side by side.
In the configuration to compression roll 20, can find out in FIG totally with the scratch device of 28 marks.This scratch device 28 can such as the liquid swashing and splash on surface 24 that distributes, to be difficult to the adhesion of basic material forming or stop compacting thus.This scratch device 28 also may be used for wiping from surface 24 basic material adhered on the surface 24 when soil compaction 10 travels forward off.
The structure of scratch device 28 is described in detail referring to Fig. 2 to 6.
Can find out in Fig. 2 to 6 totally with the framework of the vehicle region 18 before 30 marks, comprise the compression roll 20 matched.The strigil 38 of the rotating scratch device 28 of axle of the nearly level of solderless wrapped connection is installed in the region 32 below framework 30 on such as two deflection join domains 34,36.Each of these deflection join domains 34,36 is included in a junction plate 40 on strigil 38 and a junction plate 42 on framework 30.Deflection connecting bolt 44 runs through two junction plates 40,42 and therefore can be connected on framework 30 with deflecting by strigil 38.Butterfly spring 46 can arrange around deflection connecting bolt 44 and to support about strigil 38 and framework 30 in other words about junction plate 40,42 with its each leg and therefore by pre-tensioner for strigil 38 in work inflection point, in this work inflection point, strigil is in the surface 24 of compression roll 20 and contacts.
Strigil 38 can be configured with the scraper blade 48 of contact surface 24 in work inflection point and reinforce the strigil beam 50 of strigil 38 on the whole, and scraper blade 48 can be such as fixedly connected with this strigil beam by thread connection.
That overall 52 marks are set in the region stretching out in framework 30 in side of such as strigil 38 and be configured to foot rest in an illustrated embodiment action bars.In FX 54, this action bars is connected to strigil 38.Therefore such as gusset plate 56 can be set on strigil beam 50, this gusset plate extends between the fringe region of this side of deflection join domain 34 and strigil 38 also therefore can ensure action bars 52 on strigil 38 for reversing also stable connection.Action bars 52 provides pedal tread 60 in force region 58, and this pedal tread can be configured with anti-skidding structure 62, such as rib structure or similar item, to stop the landing of the footwear be pressed onto on force region.
Due to the fixing connection of action bars 52 on strigil 38, action bars 52 causes action bars 52 and strigil 38 jointly around the deflection of the yawing axis by deflecting the strigil 38 that connecting bolt 44 is determined in the force in force region 58.The pre-tensioner effect that strigil 38 overcomes butterfly spring 46 at this is unclamped from the surface 24 of compression roll 20.In order to lock strigil 38 in this location that is in shut-down inflection point, scratch device 28 comprises totally with the locking device of 64 marks.The locking member 66 being configured to stop pin can be moved along the direction of pin longitudinal axis and rotatably be received around pin longitudinal axis in this fairlead 68 such as fixed by welding, thread connection or similar item on action bars 52.This by unshowned Pre-tension spring in the various figures or similar item locking member 66 is pre-tensioner to the direction of active position, in this active position, the keyed end 70 of locking member 66 can be embedded in the lock opening 72 of pairing locking member 74 fixing on framework 30.What pairing locking member 74 arranged cam-like works pushes inclined-plane 76 open, and when strigil 38 deflects from work inflection point to shut-down inflection point, the keyed end 70 of locking member 66 is bearing in this and pushes open on inclined-plane.Overcome above-mentioned pre-tensioner effect by cam effect locking member 66 to move along its longitudinal direction, this means moving right of locking member 66 in Figure 5.This move continue deflection time continue so long, until keyed end 70 is located by the lock opening 72 such as becoming elongated hole-shape to form.Make it embed in lock opening 72 with its keyed end 70 by locking member 66 pre-tensioner and when continuing deflection or when back deflecting gear on the wall region of the encirclement lock opening 72 of pairing locking member 74.So this deflection exceeding the shut-down inflection point determined by lock opening 72 not only stoping deflection but also prevention to work inflection point to continue.In order to stop the back deflection to work inflection point, the backstop being substantially provided as planar or seamed edge shape formation is enough, that is must not need lock opening.But the setting of lock opening is provided in the advantage that two yawing moments lock.
In order to cancel deflection locking, the actuating element that can arrange on locking member 66 or control handle apply pulling force, and this pulling force overcomes pre-tensioner effect and is pulled out from lock opening 72 by the keyed end 70 of locking member 66.Once keyed end 70 no longer embeds in lock opening 72, just strigil 38 is caused automatically to deflect back the work inflection point of this strigil by the pre-tensioner effect of butterfly spring 46.If then abandon being applied to the pulling force on locking member 66, then this locking member moves on to its active position again, and locking member 66 can be made in this active position when the force again then of action bars 52 to be again in locking phase mutual effect with pairing locking member 74.
As mentioned above, locking member 66 also can around the longitudinal axis of this locking member in the fairlead 68 be fixed on action bars 52.Fairlead 68 is such as then provided with into the cam surface 80 of ellipticity formation by cutting sth. askew of tubular structure portion in this example at the end regions away from action bars 52.Pre-tensioner in the locking member 66 of active position, such as, rotation by applying the locking member 66 that rotatory force causes to actuating element 78 causes actuating element 78 move along cam surface 80 and make locking member 66 move to the direction of un-activation position from the active position of this locking member simultaneously.This also may be used for cancelling the locking interlocking in lock opening 72 to the rotary action of locking member 66, so again discharge locking member 66, thus makes this locking member again return active position after the pre-tensioner effect of this locking member.Here can such as design like this, namely the 90 ° rotations of locking member 66 from its maximum location shifted on pairing locking member 74 cause such movement of locking member 66, namely it no longer embeds in lock opening 72, therefore be cancelled with the locking phase mutual effect of pairing locking member 74, and guarantee in addition, when then discharging locking member 66, this locking member returns to its maximum location shifting to pairing locking member 74 again.Locking member 66 be rotated further further and also with its occur continue to move axially time, then the actuating element 78 along cam surface 80 movement can be made to cross the dead point of cam surface 80 and such as be embedded in the gap or recess in cam surface 80 arranged in fairlead 68.In such location, locking member 66 is in its un-activation position, and in this un-activation position, it is so retracted away from ground and also keeps being pulled, and makes this locking member be no longer possible with the locking phase mutual effect of pairing locking member 74.When not needing when strigil 38 deflects out from its work inflection point or do not wish to manufacture positive lock, such location of locking member 66 can be selected.
If the possibility of the locking of locking member 66 and pairing locking member 74 again will be set up, then can such as by the tractive on actuating element 78 or/and the effect of rotating makes the recess of this actuating element and fairlead 68 or breach depart to rabbet, and with such degree, the dead point that cam surface 80 is formed is crossed, and the pre-tensioner locking member 66 of following locking member subsequently automatically returns active position again.Can advantageously at this, cam surface 80 forms symmetrical, and therefore never active position starts tractive or makes it possible to get back to active position along arbitrary rotation direction twist-lock element 66.
By action bars 52 and locking device 64 structural associate can realize deflect or lock or discharge lock time scratch device 28 very easy maneuverability, thus such as promote action bars 52 with pin and with hand or also indulge locking member 66 by foot operation, such as to cancel locking interlocking or locking member 66 sent back to its active position or make this locking member move to the direction of its un-activation position, and do not need operating personnel to bend, therefore obtain the favourable operability of ergonomics.
Fig. 2 illustrates, can arrange in the configuration to same compression roll two such scratch devices 28 or 28 '.Below that also describe in detail and be arranged in the region near ground with the scratch device 28 shown in larger details at this in Fig. 3 to 6, at the above the ground maximum height reaching 40cm in region 32 such as below framework 30, thus be here be easy to the manipulation of pin and be possible in ergonomics.Second scratch device 28 ' is arranged in region above framework 30 82 and rotating shaft about compression roll 20 is located in scratch device 28 close to diametrically contraposition, thus two scratch devices 28,28 ' can realize their function as well as possible distributively along the circumference of compression roll 20.Because scratch device 28 ' is positioned further from the region on basis, here advise, the action bars matched for this scratch device 28 ' is configured to handle, the strigil of this scratch device 28 ' can be made by this handle to shift out from the work inflection point of strigil by the effect of tractive.The structural form of implementation of scratch device 28 ', particularly also about locking device, can as above to describe about scratch device 28 formation.
If arrange two such scratch devices in the configuration to a compression roll, then preferred the action bars matched for them to be arranged on the same side of soil compaction.If soil compaction comprises multiple compression roll, therefore such as compression roll is formed in vehicle region above and compression roll is formed in vehicle region below, and be the one or more scratch device comprising corresponding operating bar of each configuration of these compression rolls, then also preferred all such action bars is arranged on the same side of soil compaction, thus operating personnel such as can utilize all operations bar very fast in order to implement cleaning work, to make whole strigil be in their shut-down inflection point and be locked in these shut-down inflection points.
Certainly diverse change can be carried out in the above-mentioned form of implementation of scratch device.Therefore pairing locking member can be formed like this in the configuration to such scratch device, namely by providing multiple lock opening can keep multiple shut-down inflection point by locking.In addition likely, form pairing locking member like this, open from deflection the compression roll shut-down inflection point farthest matched at strigil and do not meet maximum accessible shut-down inflection point.So such as passing through in the accessible shut-down inflection point of locking, strigil can have the spacing of the surface about 50mm to the compression roll matched, and until the maximum deflection of the spacing of such as 60mm is possible.Certainly, strigil itself structurally also can form by different modes and can more than only two deflection join domains in be rotatably supported on the superstrate portion of soil compaction.
